GAS LIGHTER.

Specification of Letters Patent.

Application filed September 19, 1908. Serial No. 453,847.

To all whom it may concern:

Be it known that 1, Wilson I). t). \Vnicu'r, a citizen of the- UnitedStates, and a resident of Germantown, Philadelphia, in the county ofPhiladelphia aml State of Pennsylvania, have invented a new and improvedGas- Lighter, of which the following is a full, clear, and exactdescription.

My invention relates to gas lighters, and has for its object to providean electrical gas lighter which is constructed in the following manner.7 v

A spark coil and battery cells are disposed in a casing, to which isattached a hollow standard, at the top of which there is a stationaryelectrode and also a spring electrode,

the latter being attached to an electrical conductive rod which is heldin bearings in the hollow stem. A wire from-the spark coil leads to thestationary electrode in a plate in the casing which is insulated fromthe said casing. The casing is of conductive metal and the rod is inelectrical.connnunication with the casing. 'l. he battery cells havecontact plates at their terminals, which are adapted to complete thecircuit between them and between the said plate in communication withthe spark coil, and also with a spring which is in electricalcommunication with the metallic casing to complete the circuit with therod.

In this specification I will describe thepreferred form of myinventiom'but I do not limit myself thereto as I consider myselfentitled to all'forms and embodiments of the invention which may be heldto fall within the scope of the appended claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which'similar characters of re terence indicatecorresponding parts in all the figures, in which F'gure 1 is a sectionalelevation of the invention; Fig. 2 is a sectional view on the line 22 ofFig. 1; and Fig. 3 is a sectional view on the line 33 of Fig. 1.

By referring to the drawings, it will be seen that a cylindrical casing1 is provided, which has caps 2 and 3 which are adapted to screw on itsterminals. In the casing 1 there is a partition 4 which is adapted toseparate a spark coil 5 from battery cells 6. To the casing is secured ahollow standard 7, metallic brackets 8 being provided to hold thestandard in place relatively to the easing. J ournaled in the standard 7is an electrical conductive rod 9, which is in electrical communionlionwith the casing, by means of its bearings, the hollow standard and thebrackets, all of which are of conductive metal. At the top of thestandard there is secured av member 10, which is preferably disposed atright angles to the standard, this member-l0 having a guard 11 disposedthcreovcr to protect the electrodes. One of these electrodes isstationary and is insulated from the member 10 by insulating material12, the stationary electrode 13 being in electrical communicationwiththe spark coil 5 by means of an insulated wire 14. A springelectrode 15'is secured to the rod 9 and is so disposed that when therod 9 is moved up and down, the spring electrode 15 will bring about amake-and-break contact with the stationary electrode 13. An upright stop16 is disposed at one side of the spring elect-rode 15, this-stop beingadapted to prevent the spring electrode 15 from moving out of operativeposition. Another wire 17' from the spark coil 5 passes through thepartition 4: and is in conm'iunication with a contact plate 18. Thepartition 4 is of insulating material. in order to prevent a shortcircuit between the contact plate 18 and the casing. T he positive andnegative poles of the battery cells (3 are eonnected by contact members19, and an electrical communication is made between the lower batterycells 6 and the casing 1, by means of an electrical conductive spring20. The hollow standard 7 is open at the bottom, and the electricalconnective rod 9 projects through the opening, a spring 21 secured tothe rod 9 pressing against the partition 22 to hold the rod down, and alever 23 pivoted to an extension 2% of the hollow standard 7 isprovided, to bear on the lower terminal of the rod 9 to press itupwardly.

In using my invent-ion,=the cap 3 is removed from the casing 1, and thebatteries are then inserted in the casing in the usual manner, theconnections between the battery cells being obtained by means of thecont-act members 19, the upper contact member being in communicationwith the contact plate 18, which completes the communication between thebattery cells and the spark coil 5. The spring 20 is then inserted atthebottom of the casing and the cap 3 is screwed in place. The lighter isthen adapted to beused, and when brought in communication with-propergas mixture, the rod 1) may be Patented Aug. 31, 1905).

ard, a stationary electrode secured moved upwardly by means of the lever23, which will draw the movable spring electrode into contact with thestationary electrode 13, and when the lever is drawn away the spring 21will draw the rod down, thus breaking the circuit and producing the de-.

sired spark.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

In a gas lighter, a casing in which are disposed a spark coil, andabattery, a standard, which is secured to the casing, an open framesecured to the top of the hollow standto the open frame having asubstantially horizontal upper terminal, a rod journaled in the hollowstandard, an electrode secured to the rod substantially at right anglesthereto and being disposed trode, a stop, second elect-rode in the pathof the first named electrode, means to hold the rod yieldinglydownward," a lever having a shoulder, which is adapted to engage thelower terminal of the rod to move the rod upwardly, and an electricalcircuit in which the spark, the coil, the battery, the electrodes,

and the rod form units.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
